DVS Series
The DVS Series is a programmable Natural Convection Oven capable of six-pattern program operation. It combines PID temperature control with multiple safety and diagnostic functions, and a note on the product page cautions that placing heat-generating samples inside may prevent normal temperature control.

Manufacturer: Yamato — Japan
Overview
The DVS Series is a programmable Natural Convection Oven capable of six-pattern program operation. It combines PID temperature control with multiple safety and diagnostic functions, and a note on the product page cautions that placing heat-generating samples inside may prevent normal temperature control.
Program Patterns
The oven is equipped with six patterns of program controllers (30 steps ×1, 15 steps ×2, 10 steps ×3).
Sub-Functions
It is equipped with sub-functions such as overheating prevention temperature setting, calibration offset function, key lock function, and program repeat function.
Safety Measures
A self-diagnosis circuit checks for temperature sensor error, heater disconnection, memory error, internal communication error, temperature input circuit error, and SSR short circuit, alongside an overheating prevention device and overcurrent leakage breaker.
